Abstract: Based on the cleaner production development planning for chromium salt industry in China，the key issues and parameter control in producing sodium dichromate with non-calcium roasting process were mainly introduced.From a practical point of view，technical references were provided for the new，expansion or technological transformation projects of Chinese chromium salt industry enterprises.At the same time，it was pointed out that the non-calcium roasting technology in China needed to be further improved in fields of automation engineering，system engineering，and environment engineering.Currently，the responsibility of technical innovation has been transferred to enterprises themselves and the chromium salt enterprises have become the innovation executors and developers from the high-tech acceptors.  

Key words: non-calcium roasting, chromite, cleaning production, sodium dichromate, chromium salt
